From point of lay a valuable programme in breeder layers has been developed:
125 ppm Tiamutin active ingredient (AI) in drinking water 3 days/month
- equivalent to 250 ppm Tiamutin (AI) in feed 3 days/month.
This is achieved with approximately 40g Tiamutin (AI)/1000 hens/day. Dosage rate = 12.5mg/kg bodyweight).
Over the whole laying period (42 weeks) the hen receives only 1.25g Tiamutin (AI), an approximate cost of 1-2 chicks/hen.
